REPRODUCER.

Application tiled July 19, 1900.

Be it known that I, EDWARD KARLOW, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, county and State of NewYork, have invented a new and Improved Phonograph-Reproducer, of which the following is a full, clear, and exact description.

My invention relates to phonograph-repro-` ducers, and has for its object to provide a device of this class in which the jarring and metallic sounds so troublesome in many reproducers will be eliminated and a clear loud i tone obtained.

graph or graphophone provided with my improvedreproducer. Fig. 2 is an end view thereof. Fig. 3 is a central sectional side elevation of the reproducer drawn upon an en- Fig. 4 is an inverted plan of the reproducer. Fig. 5 is a sectional eleva-` Fig. 6 is a sectional plan on line 6 6 of Fig. 2, and Figf` is a detail `perspective view of the support `for the arm carrying the reproducing-point. 35`

The phonograph or graphophone itself may be of any suitable construction. In the drawings I have shown the cylinder A holding the record B and driven by means of the belt C, while gearing D drives .the usual feedscrew E, engaging the carrier F of the repro-` ducer. I prefer to so construct my repro-` ducer that it will fit the ordinary reproducercarriers after removal of the reproducer, which presents no difficulty, since the reproducer is commonly removable from its `carrier.

F is the socket or tube which normally receives the ordinary reproducer, (but is without function in my invention,) and F2 is the tube which is ordinarily connected with the horn or hearing-tubes.

YK2 for manipulating the pin;

Serial No. 24,186. (No model G is the arm used in ordinary graphophones for throwing the reproducer upon and o the record and connecting the carrier operatively with the feed-screw or disconnecting it therefrom, all these parts being of the usual construction or at least they form no part of my present invention. The arm G, however,

in my invention only serves to establish or interrupt the driving action of the feed-screw on the carrier.

My improvement comprises a support or frame H in the nature of a curved plate or bracket and having at its lower end a socket H and lugs H2, adapted to lit, respectively, upon the tube F2 and upon the body of the carrier F, as shown in Figs. l and 2. In this manner the frame H is rigidly yet removably supported on the carrier F. At the upper "end of the frame or support H is rigidly secured a tube H3, projecting rearwardly therefrom and adapted to receive the end of a horn, such as I. In alinement with the tube H3 another tube H4 projects from the support I-I, but forwardly, and to said tube H4 is pivoted about a horizontal axis J 2 a spherical portion J located at the rear of a swinging tube .Lwhich is adapted to carry the reproducer, as will be described presently. The swinging tube has an arm J3 extending downwardly therefrom and adapted to be engaged by a pin K, mounted to slide in a socket H5 of the support H land engaged by elastic frictionjaws HF, attached to the rear of said support. The pin has agroove K/ at its rear end to hold it in the forward position when the jaws H6 engage said groove and an eye or handle At the top of the swinging tube J is located a bearing-plate L, made of leather or light material, and a similar plate L' is provided at the top of the support H-for instance, upon the tube H4.

-From the support H projects forwardlya U- N, having at its center a screw-threaded bearing for a screw O, the end of which is adapted to engage either of the bearing-plates L or L'.

The reproducer proper comprises a casing P, with a tube P, adapted to t over the tube J of the support, and a sound-passage P2.

IOO

lThe casing has a circular ange P3, forming aholder for the diaphragm Q, whichl is spaced from the casing at its edge by a rubber ring R. Adjacent to the tube P the casin g has two spaced lugs P4, recessed to receive the ends of two elastic plates S, preferably of soft rubber, the inner ends of which are slightly spaced from each other. To theseplates is secured or cemented a plate or foot T', disposed at the end of the arm T, which carries the usual reproducing-point U. As the arm is cemented to therubber plates S, it has only a very slight lateral mobility. The inner end of the arm T engages a pin V, connecting two spaced fork members W, projecting from the center of the diaphragm Q, as usual. between these members is somewhat greater than ordinarily, so that the inner end of the arm T, which is free to slide transversely on the pin V, may not be jarred into engagement with the fork members. It will also be observed, Fig. 2, that the parts are so arranged that the reproducing-point U will be exactly on top of the record B.

The operation is substantially thel usual one, the pin K being employed to hold the reproducer away from the record or lower it `upon the same, while the arm G throws the carrier F into or out of operative connection with the feed-screw E.v The sound is very strong as it passes from the diaphragm Q di rectly to the horn I, with only one bend or deflection in the passage P2. As the arm T does not engage any metal at and is cemented to the rubber plates S, it cannot rattle at that point, while it is yieldingly mounted, so as to be capable of following the vibrations of the point U. The arm T cannot engage the members of the fork W either, as the plates S allow only a very slight lateral movement of the said arm.

Should any imperfect records produce screeching sounds, (owing to too strong vibrations of the reproducing-point U,) this can be remedied by placing the screw O upon the bearing-plate L, so as to press the reproducer more forcibly down uponthe record by the tension of the springs M, which can be adjusted by turning the screw O. When not in, use, the screw is placed on the bearingplate L.

While I have shown two separate plates S Vand while this arrangement is preferable on account of its greater elasticity, I might em'- ploy a single platey extending entirely across the space between the ears or lugs P4. Also instead of making the support H with the lugs H2 and socket H to fit ordinary carriers F, I may of course when constructing new machines make the support H in one with the carrier F, omitting the tubes F and F2. These and other changes may be made without departing from the nature of my invention.

The distance canots `I desire it to be understood that the terni phonograph where it occurs in the claims is to be interpreted as meaning, broadly, a talking-machine. A

Having thus described my invention, I claim as new and desire to secure by Letters Patent- Y l. A phonograph-reproducer, provided with a diaphragm, an arm having one end loosely connected with the diaphragm and provided at its other end with a foot and between its ports carried by the body of the reproducer,

.said plates extending inwardly toward each otherfrom their supports and to which the foot of the arm is secured between saidvsup ports, as and for the purpose set forth.

The combination of a phonograph-reproducer, a support to which said reproducer is pivoted, a spring one end of which is attached to the support, a bar to which the other end of the spring is secured, and a screw passing through said bar and arranged to engage the pivoted reproducer.

4. The combination of a phonograph-reproducer, asupport to which said reproducer is pivoted, springs each having one end attached to the support, an arched bar or hoop to the ends of which are secured the other ends of the springs, and a screw passing through the central portion of said hoop and arranged to engage the reproducer. l

5. Aphonograph attachment, provided with 'a support having an attaching-socket, a reproducer pivotally connected with said support, and a holding device movably secured to the support, and arranged to keep the reproducer in a raised position.

6. vA phonograph attachment,provided with a support having an attaching-socket and .lugs arranged adjacent to said socket, and a reproducer carried by the said support on the side opposite to that on which the lugs are arranged.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD KARLOW.
